122. Every certification required for the purpose of a partial actuarial valuation must reflect the financial position of the plan at the date of the actuarial valuation, estimated on the basis, in particular, of the actual rate of return of the pension fund, changes in interest rates determined on a solvency basis and the contributions actually paid into the pension fund since the last complete actuarial valuation of the plan.
If a partial actuarial valuation pertains to the amendments to a pension plan, it is limited to the determination of the value of the additional obligations arising from any amendment considered for the first time in the valuation or to the determination, on a funding basis, of the variation in the current service contribution arising from the amendment. The determination of the value or of the variation must be based on the same assumptions and methods as were used for the most recent complete actuarial valuation, unless those assumptions and methods are not appropriate in view of the nature of the amendment made to the pension plan.
However, if the amendment to the pension plan increases the pensions already in payment and the additional obligations arising from the amendment are guaranteed by an insurer at the date on which the actuarial valuation report is prepared, the value of the obligations may be assumed to correspond to the premium paid to the insurer, discounted at the date of actuarial valuation according to the rate of return of the pension fund.
